“…[11] In our study, we showed that the IT diameter increased linearly with increasing CRL, which was consistent with the previous reports. [6,12,13,19] A weak positive correlation was found between increasing CRL and IT in some studies like our study, [11,17] but high correlation was noted in other studies. [6,19] The main difference in our report was the higher sample size than previous reports.…”

Objective: The aim of this study was to evaluate normal reference ranges of intracranial translucency (IT) diameter, and to obtain its nomogram in normal fetuses, during 11-13 weeks of gestation.Methods: This was a retrospective data evaluation of first trimester ultrasound scans. A total of 2417 singleton pregnancies were included in the study. IT was measured in the nuchal translucency plane. Nomogram and formula of IT diameter were defined according to crown-rump length (CRL). Results:The IT diameters were measured successfully in 2250 fetuses (93.1%). The mean maternal age was 31.8±4.0 years. The mean CRL was 62.0±6.9 mm. The mean IT diameter was 1.83±0.29 mm. The linear tendency was determined according to the following formula: IT (mm)= 0.54 + 0.02 × CRL (mm); r 2 =0.24. Conclusion:We presented the feasibility and a nomogram of IT diameter at 11 to 13 +6 weeks of gestation in our population to be used for early prediction of neural tube defects.

“…In 2016, Molina-Giraldo et al established a nomogram for the IT in a Latin-American population. [11] They reported a median IT of 1.7 mm (interquartile range, 1.42-.2 mm) in fetuses with a CRL between 45 and 84 mm, which is the measurement used to determine IT presence or absence.…”

Intracranial Translucency, Its Use as a Potential First Trimester Ultrasound Marker for Screening of Neural Tube Defects

The objective of the study was to describe a case-series of neural tube defects (NTD) with an abnormal intracranial translucency (IT) detected during the first-trimester ultrasound scan, performed on a low-risk obstetric population in Mexico. Certified Fetal Medicine specialists performed all US scans; the IT was assessed using the mid-sagittal view of the fetal head, which is already systematically used for nuchal translucency and nasal bone evaluation. During the study, we were able to find that eight fetuses had an absence of the intracranial translucency, out of which two were reassessed at 14 weeks′ gestation and IT was normal, six of them were later diagnosed to have an NTD that consisted in spina bifida aperta (n = 5) and encephalocele (n = 1). Conclusion: As previous studies have shown, IT evaluation during the first-trimester US routine scan may be a useful screening marker for early detection of NTDs.

“…1520 fetüsü değerlendirilmiş, CRL ortalamasını 65 mm (45-84 mm), IT ortalamasını 1.7 mm (0.7-3.4 mm) olarak hesaplamışlardır. Çalışmamızdakine benzer olarak IT ile gestasyonel hafta arasında lineer ve pozitif bir korelasyon saptanmıştır (IT=0,043xC-RL-0,815) [17]. Adiego ve ark.…”

Amaç: 11-14. gebelik haftaları için intrakranial translusensi (IT) nomogramı oluşturulması ve IT ölçümlerinin gebelik günleri, baş popo mesafesi ve bipariyatel çap ile olan ilişkisinin değerlendirilmesi. Gereçler ve Yöntem:Kliniğimize başvuran birinci trimester'deki 119 tekiz gebe çalışmaya dâhil edildi, bu gebelerde fetüslerin IT genişliği değerlendirilip gebelik günü, b aş popo mesafesi (CRL) ve bipariyatel çap (BPD)ile olan ilişkisi araştırıldı. Yapısal veya kromozomal anomali saptanan fetüsler ve çoğul gebelikler çalışma dışı bırakıldı.
